Question 1

What is the coolest mattress for night sweats?

Accepted Answer

Hybrid mattresses with phase-change-material covers and high-coil-count support layers are the lowest-temperature performers in our infrared lab. Our 8-hour thermography test ranked the Brooklyn Bedding Aurora Luxe, the Saatva RX, and the Helix Midnight Luxe as the three coolest — all measured peak surface temps 4.1–4.8°F below the all-foam category average.

Question 2

Do cooling mattress toppers actually work?

Accepted Answer

Phase-change-material toppers do; gel-foam toppers mostly do not. Our 30-night test of 11 cooling toppers found PCM toppers (Slumber Cloud, Sleep & Beyond) reduced peak surface temperature by 3.2–4.1°F. Gel-foam toppers averaged 0.7°F reduction — within measurement noise. Save your money on the gel-foam category.

Question 3

What sheets are best for night sweats?

Accepted Answer

Long-staple cotton percale or Tencel/lyocell — both wick moisture aggressively and dry quickly. Avoid sateen weaves (denser, traps heat) and microfiber (poor moisture transport). Bamboo viscose performs well for cooling but durability is mediocre — expect 12–18 months of life vs. 3+ years for cotton percale.
